Article 130.
The federal powers shall exercise the supervision required by law in matters relating to religious worship and outward ecclesiastical forms.

The law does not recognize any personality in religious groups called churches.

Ministers of denominations shall be considered as persons who practice a profession and shall be directly subject to the laws enacted on such matters.

Ministers of denominations may never, in a public or private meeting constituting an assembly, or in acts of worship or religious propaganda, criticize the fundamental laws of the country or the authorities of the Government, specifically or generally. They shall not have an active or passive vote nor the right to form associations for religious purposes.

Permission to dedicate new places of worship open to the public must be obtained from the Secretariat of Government, with previous consent of the government of the State.
